Description

Fixtures and fixing devices

The present invention relates to a fixture and a fixing device for fixing a solar module to an installation location.

For some time now, photovoltaic power generation systems have been known that generate power using, for example, multiple photovoltaic modules fixed to the roof of a house. As a technology for fixing solar modules to a roof, a base member is fixed between two adjacent solar modules on the roof, and a holding member for holding the edges of the two adjacent solar modules is attached to the base member. A technique of fixing with bolts and nuts is known (see Patent Document 1, for example).

Japanese Patent Application Laid-Open No. 2018-109322

However, fixing with bolts and nuts had the following problems. That is, in order to confirm whether or not the bolts and nuts have been forgotten to be tightened, it is conceivable that the operator manually confirms the looseness of the bolts and nuts, but this is inefficient.

Therefore, it is an object of the present invention to provide a fixing device that can improve the efficiency of confirming whether or not a fixing member for fixing the fixing device to an object to be attached has been left unfixed.

The fixture is a fixture for attaching a plate-like solar module to an attachment target, and includes a base portion fixed to the attachment target by a fixing member, and a regulation provided at the base portion for regulating movement of the solar module. and a deforming portion provided between the base and the attachment target side of the base and deformed by being pressed by the base when the base is fixed to the attachment target, wherein the base is fixed to the mounting object, the deformation portion is deformed so that the restricting portion is displaced to enter a first state in which movement of the solar module can be restricted, and the base portion is fixed to the mounting object. In the non-fixed state, the restricting portion is in a second state different from the first state.

According to the present invention, it is possible to improve the efficiency of confirming whether or not the fixture that fixes the fixing device to the attachment target has been forgotten to be fixed.

Next, the worker confirms that the bolts 24 and nuts 25 of the eaves side fixing device 4 are tightened. When the bolt 24 and the nut 25 are fastened, the restricting portion 61 is in the first state P1. When the bolt 24 and the nut 25 are not tightened, the restricting portion 61 is in the second state P2. The operator recognizes that the bolt 24 and the nut 25 are fastened when the restricting portion 61 is in the first state P1. When the restricting portion 61 is in the second state P2, the operator tightens the nut 25 to fasten the bolt 24 and the nut 25 .

Next, as shown in FIG. 2, the operator inclines the first solar module 2A and inserts the end portion between the third restricting portion 65 and the third placement portion 62a. Next, the operator lowers the ridge-side end portion of the first solar module 2A and places the first solar module 2A on the first mounting portion 48 and the third mounting portion 62a. When the first solar module 2A is placed on the first mounting portion 48 and the third mounting portion 62a, the first projecting portion 48a breaks the plated layer of the frame 11 and comes into contact with the base material. and the support member 22 are electrically connected.

Next, the operator places the ridge-side end of the lower surface of the first solar module 2A on the second placement of the support member 22 of the fixing device 3 fixed to the ridge side of the first solar module 2A. It is placed on the part 50 . The operator adjusts the positions of the support member 22 and the pressing member 23 by moving the supporting member 22 and the pressing member 23 along the groove 35 . When the first solar module 2A is placed on the second placement portion 50, the second protrusion 50a breaks the protective layer of the frame 11 and comes into contact with the base material, so that the base material of the frame 11 and the support member 22 are separated. is conducting.

Next, the worker fastens the bolts 24 and nuts 25 of the fixing device 3 to fix the support member 22 and the pressing member 23 to the base member 20 . When the bolt 24 and the nut 25 are tightened, the third restricting portion 65 and the fourth restricting portion 66 change from the second state P2 to the first state P1. Next, the worker confirms that the bolt 24 and the nut 25 are fastened in the same manner as the eaves side fixing device 4 . When the bolt 24 and the nut 25 are not fastened, as shown in FIG. 8, the third restricting portion 65 and the fourth restricting portion 66 are in the second state P2.

Next, the operator inserts the second solar module 2B between the third restricting portion 65 and the third placement portion 62a in the same inclined posture as the first solar module 2A. Next, the worker lowers the ridge-side end portion of the second solar module 2B and places the second solar module 2B on the first mounting portion 48 and the third mounting portion 62a. When the second solar module 2B is placed on the first mounting portion 48 and the third mounting portion 62a, the first projecting portion 48a breaks the protective layer of the frame 11 and comes into contact with the base material. and the support member 22 are electrically connected.

Next, the worker further fixes the second solar module 2B by the fixing device 3 fixed to the ridge side in the same manner as the fixing device 3 to fix the ridge-side end of the first solar module 2A. The ridge side end of the Thus, the work of fixing the first solar module 2A and the second solar module 2B using the fixing device 3 and the eaves side fixing device 4 is completed.

The worker fixes the plurality of solar modules 2 to the roof 200 by repeating the same process for the third and subsequent solar modules 2 from the eaves side. A row of multiple solar modules 2 aligned in the third direction V3 is electrically connected via the support members 22 of the multiple fixing devices 3 and the multiple frames 11 . For example, the worker attaches a ground wire to the supporting member 22 of the fixing device 3 closest to the ridge, and collectively grounds the plurality of solar modules 2 arranged in a row from the eaves side to the ridge side. As described above, the operation of fixing the plurality of solar modules 2 to the roof 200 using the plurality of fixing devices 3 and the plurality of eaves side fixing devices 4 is completed.

Next, an example of the work of replacing the bolts 24 with the base member 20 fixed to the roof 200 will be described. When replacing the bolt 24, the operator first removes the nut 25 and the pressing member 23 from the threaded portion 24c. Next, the operator moves the head portion 24 a to the first portion 37 . Next, the operator removes the bolt 24 from the base member 20 by moving the head portion 24 a upward through the first portion 37 . Next, the worker attaches the bolt 24 to the base member 20 by moving the head portion 24 a of the other bolt 24 downward through the first portion 37 . Thus, the replacement work of the bolt 24 is completed.

In the fixing device 3 configured as described above, when the bolt 24 and the nut 25 are not tightened, the pressing member 23 is tilted by the biasing portion 44, so that the restricting portion 61 is in the second state P2. Therefore, the operator can recognize that the bolt 24 and the nut 25 are not fastened by visually confirming that the restricting portion 61 is in the second state P2. Therefore, the operator can improve the efficiency of confirming whether or not the bolt 24 and the nut 25 have been forgotten to be tightened, that is, whether or not the fixture 6 has been fixed.

Furthermore, the biasing portion 44 has a restoring force. Therefore, the nut 25 is biased through the base portion 60 when the restricting portion 61 is in the first state P1. Therefore, loosening of the nut 25 can be prevented.

Furthermore, the fixing device 3 fixes the support member 22 to the base member 20 together with the pressing member 23 using bolts 24 and nuts 25 . Therefore, the support member 22 and the pressing member 23 can be prevented from slipping, so the efficiency of fixing the solar module 2 can be improved.

The second restricting portion 63 is formed so as to be able to come into contact with the upper surface portion 13 of the solar module 2 on the ridge side and the eaves side. Therefore, movement of two solar modules 2 can be restricted by one fixing device 3 .

The upper surface 26 of the base member 20 is formed in a plane parallel to the sheathing board 202 while the base member 20 is fixed to the roof material 201 . Therefore, the solar module 2 can be fixed parallel to the sheathing board 202 .

Furthermore, since the base member 20 can move the support member 22 and the pressing member 23 in the temporarily fixed state along the groove 35, the positions of the supporting member 22 and the pressing member 23 can be changed during the fixing work of the solar module 2. Adjustable. Therefore, since it is not necessary to remove the base member 20 when adjusting the positions of the support member 22 and the pressing member 23, the efficiency of fixing the solar module 2 can be improved.

Furthermore, the base member 20 has a configuration in which the upper surface 26 is parallel to the sheathing board 202 due to the vertical length of the vertical wall portion 34, so the configuration of the base member 20 can be simplified. Furthermore, the base member 20 is provided with a mark 26a. Therefore, the efficiency of the work for fixing the base member 20 can be improved.

Furthermore, the groove 35 has a first portion 37 through which the head portion 24a can be inserted. Therefore, the bolt 24 can be replaced without removing the base member 20 from the roof 200. - 特許庁Furthermore, the base member 20 includes a restricting portion 36 that restricts rotation of the bolt 24 . For this reason, the efficiency of fastening work of the bolt 24 and the nut 25 can be improved. Furthermore, the restricting portion 36 includes a pair of vertical wall portions 36 a formed on the pair of edges of the groove 35 . Therefore, the configuration of the restricting portion 36 can be simplified.
